Let’s check out the types of grammar mistakes.

Prepostseo grammar checker removes

1. Active & Passive voice errors

Many people think that any particular sentence that consists of verbs like is, was, were, etc. is a passive voice but this is not actually true. A sentence that will be converted to a passive voice should have an object.

Active voice: “The history class witnessed the fort.”

The Passive voice transformation,

Incorrect: “The history class has witnessed the fort.”

Correct: “The fort was witnessed by the history class.”

Always keep in mind that all passive voice sentences have a form of a verb like was, were, etc., but not all sentences that consist of those verbs are passive. We should have to be very careful while writing passive voice sentences in our articles.

2. Spelling Mistakes

This tool efficiently identifies and removes spelling mistakes. Spelling mistakes in an essay or article create a very bad impact on the mind of readers. The content should be clean from all types of spelling mistakes.

Incorrect: “Jonas can dive in the see.”

Correct: “Jonas can dive in the sea.”

Spelling mistakes can easily be avoided if articles and content should be revised properly. Usually, most of the spelling mistakes will occur if the article is not revised properly.

3. Redundant Expression

The redundant expression is nothing but using the same keywords or words repeatedly whose meanings are the same. The redundant expression should be avoided as much as possible. They will affect the efficiency of the paragraph.

Incorrect: “We can completely book the hotel floor fully.”

Correct:We can completely book the hotel floor.”

The above incorrect expression will create a sense of redundancy. The meaning of the words “completely” and “fully” is the same but both words occurred in the sentence for the same context. Our tool removes this type of errors very precisely.

4. Verbs and Tenses mistakes

The mistakes of tenses are very common in English writing. Proper knowledge about tenses can reduce these mistakes. The proper form of verbs should be used depending on the scenario. Our tool takes care of this too.

Incorrect:We have a great party yesterday.”

Correct:We had a great party yesterday.”

5. Comma splices or fragmentation

Online sentence correction is very important for sentences to be fragmented in a proper way. The writer should clearly identify where the sentence fragmentation is needed and where to use it.

So, a comma should be inserted where necessary. Our comma checker also takes care of this type of mistake.

Incorrect: “If you are not out there. Get me a coffee.”

Correct: “If you are out there, get me a coffee.”

6. Ambiguous Pronoun References

Ambiguous usage of references of the pronoun can also affect the beauty of sentences. The writer should properly use pronoun references in sentences.

Incorrect: "Janice had a meeting with Tom, but he couldn’t meet her.”

Correct:Janice had a meeting with Tom, but Tom couldn’t meet Janice.”

It makes a sense of ambiguity in the mind of the reader who couldn’t meet.
